Stelara (ustekinumab) is a prescription drug that’s used to treat certain autoimmune conditions. The drug comes as an injectable solution. Depending on the condition, it’s usually given every 8 or 12 weeks.
Stelara is used in adults to treat certain types of the following conditions:
In addition, Stelara can be used in children ages 6 years and older who have certain types of plaque psoriasis or psoriatic arthritis.
The active ingredient in Stelara is ustekinumab. (An active ingredient is what makes a drug work.) Stelara belongs to a group of drugs called biologics. (A biologic drug is made from living cells.)
This article describes the dosages of Stelara, as well as its strengths and how to receive it.
Your dosage of Stelara will depend on several factors, including:
- the condition that you’re receiving Stelara to treat
- your body weight in kilograms (kg)
- your age
- other medical conditions that you may have
- the form of Stelara you receive
The section below lists some common dosages of Stelara. However, it’s important that you always follow the dosing schedule that your doctor prescribes. Your doctor will determine the best dosage and drug administration plan of Stelara for you.
What are the forms of Stelara?
Stelara comes as a liquid solution in a single-dose prefilled syringe or a single-dose vial. The drug can be given two ways: as a subcutaneous injection (an injection under your skin) or as an intravenous (IV) infusion. (With an IV infusion, you’ll get the medication through a vein over a period of time.)
What strengths does Stelara come in?
For subcutaneous injection, Stelara is available in a single-dose prefilled syringe or a single-dose vial.
The prefilled syringe and the vial come in a strength of 45 milligrams per 0.5 milliliters (45 mg/0.5 mL). In addition, the prefilled syringe is available in a strength of 90 mg/mL.
For IV infusion, Stelara comes in a single-dose vial that’s available in one strength: 130 mg/26 mL.
What are the typical dosages of Stelara?
Typically, your doctor will start you on a dosage based on your body weight. They may adjust your dosage over time to reach the right amount for you. Your doctor will ultimately prescribe the smallest dosage that provides the desired effect.
The information below describes dosages that are commonly used or recommended. But be sure to take the dosage your doctor prescribes for you. Your doctor will determine the best dosage to fit your needs.
Dosage for plaque psoriasis
When used for plaque psoriasis, Stelara is given by subcutaneous injection. The dosage of Stelara used for this condition depends on your body weight as shown in the table below.
| Weight range | Starting (loading) dose | Maintenance dose |
|---|---|---|
| less than or equal to 100 kg (about 220 lb) | 45 mg, followed by another 45-mg dose 4 weeks later | 45 mg once every 12 weeks |
| greater than 100 kg | 90 mg, followed by another 90-mg dose 4 weeks later | 90 mg once every 12 weeks |
Dosage for psoriatic arthritis
When used for psoriatic arthritis, Stelara is given by subcutaneous injection.
Regardless of your body weight, the starting dose of Stelara for psoriatic arthritis is 45 mg, with another 45-mg dose 4 weeks later. After these first two doses, you’ll get a maintenance dose of 45 mg once every 12 weeks. For this use, Stelara is given by subcutaneous injection.
If you’re an adult weighing more than 100 kg (about 220 lb) with psoriatic arthritis and moderate to severe plaque psoriasis, your dosage will differ. In this situation, the starting dose is 90 mg, with another 90-mg dose 4 weeks later. After that, you’ll get a maintenance dose of 90 mg once every 12 weeks.
Dosage for Crohn’s disease or ulcerative colitis
The recommended dosage for Crohn’s disease and ulcerative colitis also depends on body weight. When receiving Stelara for these conditions, you’ll receive your first dose through an IV infusion. This will help the medication work more quickly at the start of your treatment.
| Weight range | Starting (loading) dose |
|---|---|
| less than or equal to 55 kg (about 121 lb) | 260 mg (2 vials) |
| greater than 55 kg up to 85 kg (about 187 lb) | 390 mg (3 vials) |
| greater than 85 kg | 520 mg (4 vials) |
After your initial dose is given by IV infusion, you’ll switch to the subcutaneous form of the drug. The maintenance dosage is 90 mg every 8 weeks, regardless of your body weight.
Is Stelara used long term?
Yes, Stelara is typically used as a long-term treatment. If you and your doctor determine that Stelara is safe and effective for you, you’ll likely receive it long term.
What’s the dosage of Stelara for children?
Stelara is approved to treat plaque psoriasis or psoriatic arthritis in children and adolescents ages 6 years and older. It’s not approved for use in children or adolescents with Crohn’s disease or ulcerative colitis.
The dosage of Stelara for treating plaque psoriasis or psoriatic arthritis in children is the same. The dosage is based on body weight, which will determine the initial dose. This same dose will be given 4 weeks later and then once every 12 weeks after that.
For children, Stelara is given as a subcutaneous injection as outlined below:
| Weight range | Dose |
|---|---|
| less than 60 kg (about 132 lb) | 0.75mg/kg |
| 60 kg or more | 45 mg |
| greater than 100 kg (about 220 lb) with psoriatic arthritis and moderate to severe plaque psoriasis | 90 mg |
If your child weighs 60 kg or more, their dosage is the same as the dosage used in adults.
If you’re administering Stelara at home and you miss a dose, inject it as soon as you remember. But if it’s been a while since your missed dose, and you’re unsure when to get your next dose, talk with your doctor or pharmacist. They can help you determine when your next dose should be.
If you need help remembering to get your dose of Stelara on time, try using a medication reminder. This can include setting an alarm, downloading a reminder app, or setting a timer on your phone. A kitchen timer can work, too.
If you receive Stelara doses at your doctor’s office, it’s important to keep your appointments. If you miss an appointment, call the office right away to reschedule.
To help make sure you don’t miss your appointment, try setting a reminder on your phone.
Stelara comes as a liquid solution that can be given as a subcutaneous injection (an injection under your skin) or as an intravenous (IV) infusion. With an IV infusion, you’ll get the medication through a vein over a period of time. A healthcare professional will administer the IV infusion form of Stelara in a medical setting, such as a doctor’s office or clinic. The infusion will be given over the course of at least 1 hour.
Most people prescribed Stelara receive it as a subcutaneous injection. Your doctor may be able to teach you or your caregiver how to give Stelara injections so you can self-inject your doses at home. If your child is receiving subcutaneous injections of Stelara, it’s recommended that a healthcare professional administer their doses.
If you receive Stelara at home, it’s important to rotate your injection sites. (Rotating injection sites means to inject into an area that’s different from where you injected the last dose.) You can inject Stelara into your upper arms, buttocks, upper thighs, or abdomen. Do not inject Stelara into skin that is red or discolored, hard, tender, or bruised.
For more information about how to inject Stelara, see the manufacturer’s step-by-step instructions.
Do not receive more Stelara than your doctor prescribes. Receiving more than this can lead to serious side effects.
What to do in case you receive too much Stelara
Call your doctor right away if you think you’ve received too much Stelara. You can also call 800-222-1222 to reach America’s Poison Centers or use its online resource. But if you have severe symptoms, call 911 (or your local emergency number) immediately or go to the nearest emergency room.
